Description
CA 0224384l l998-07-l7 NETHOD OF NANUFACTURING AIR .~KED THREADS
The invention relates to a method of manufacturing air textured threads comprising at least one ground thread and at least one effect thread, wherein at least the ground thread is drawn before it is fed together with the effect thread to a texturizing unit and wherein the texturized yarn consisting of ground and effect threads is heated.
Such methods exploit the effect that the ground thread which is drawn prior to the texturizing shrinks less than the effect thread during the heating of the texturized yarn which takes place after the texturizing unit. This has the consequence that loops formed during the texturizing of the effect thread contract during the named heating, whereby the thread ultimately obtains a relatively smooth surface in the desired manner.
In accordance with the prior art, the described method was previously only used for the manufacture of threads having a coarse fineness (tex), i. e. for the manufacture of relatively thick threads.
BRIEF SUMMARY OF THE INVENTION
An object of the invention is to so further develop the method of the initially named kind that thin, very fine threads can also be manufactured with adequate strength.
In accordance with the invention this object is satisfied in that a ground thread is used with a fineness between 80 and 200 dtex and an effect thread is used with a fineness between 60 and 165 dtex, with the effect thread being finer than the ground thread.
Through the use of ground and effect threads with the named finenesses, it is, for example, possible to make threads with a fineness lying under 200 dtex, and with a strength above 30 cN/tex without problem. In particular finenesses of the thread of approximately 130 dtex can be achieved, with strengths between 36 and 38 cN/tex being simultaneously ensured. The elongation of threads manufactured in accordance with the invention amounts, for example, to between 11 and 12 %, i.e. the texturized thread can be stretched in length by 11 to 12 % without breaking.
Through the method of the invention, very fine threads can thus be manufactured, which have both a high strength and also a high uniformity and with a high freedom from faults.
It is preferred when a ground thread is used with a fineness between 140 and 160 dtex and/or an effect thread is used with a fineness between 70 and 90 dtex. Ground and/or effect threads can each have between 36 and 144 filaments.
In order to favour the effect of the greater shrinkage of the effect thread compared with the ground thread after the texturizing unit, it is of advantage when the ground thread is drawn before the texturizing unit by a factor of 1.8 to 2.6, in particular by a factor of 2 to 2.4. Furthermore, it is of advantage if the effect thread is also drawn before the texturizing unit in addition to the ground thread, with the draw of the effect thread preferably being smaller than the draw of the ground thread. The effect thread can, for example, be drawn by a factor of 1.5 to 1.9, and in particular by a factor of 1.6 to 1.8.
It is furthermore advantageous if the ground thread and/or the effect thread is/are heated prior to the texturizing unit. The ground thread can in this respect be more strongly heated than the effect thread, with temperatures between 150~C and 240~C, and in particular between 160~C and 220~C being appropriate with respect to the heating of the ground thread.
With regard to the heating of the effect thread, temperatures between 100~C and 200~C, and in particular between 140~C and 180~C are, for example, appropriate.
For the technical realization of the method of the invention, the ground thread and/or the effect thread can in each case be guided prior to the texturizing unit over two sequential galettes. The drawing of the ground thread and/or the effect thread can then, for example, be brought about by different drive speeds of two sequential galettes, with the front galette in the forwarding direction running faster than the rear galette. In addition, or alternatively to the drawing, a heating of the ground and/or effect threads can also be brought about by means of the ~, galettes, in that at least one of the galettes respectively associated with the ground and/or effect threads is heated. In this connection the galettes can be heated to the temperatures already named above.
In order to prevent slippage occurring between the galettes and the ground and/or effect threads, the threads can each be wrapped between 5 and 20 times, in particular between 6 and 10 times, helically around a galette, so that the friction forces between the galettes and the thread are sufficiently high. Through the said wrapping a situation is also achieved, when the galettes are heated, that the threads remain in contact with the respective galettes sufficiently long, for adequate heat to be transferred from the galette to the threads.
In accordance with an advantageous embodiment of the invention, the texturized yarn is drawn after the texturizing unit. This drawing can, for example, take place by a factor of between 0.95 and 1.1, in particular between 1.01 and 1.05. The drawing preferably takes place in such a way that precisely that length of the texturized yarn which is just being heated is also simultaneously subjected to after-drawing. In this way a situation can be prevented in which the texturized yarn contracts too much during the heating. Specifically, a situation is achieved with an after-drafting factor greater than 1, in which the ground thread component of the texturized yarn is extended during the heating process. With an after-drawing factor smaller than 1, it is ensured that the ground thread components can shrink by the after-drawing factor at most.
The shrinkage of the ground thread component of the texturized yarn is thus restricted by the said after-drawing, and the loops formed by the effect thread can contract or pull together in the desired manner through the heating.
The heating of the texturized yarn after the texturizing unit is preferably effected in such a way that the temperature of the texturized yarn amounts in the named region to between 200 and 300~C, in particular to between 210~C and 260~C.
It is of advantage when the texturized yarn is also guided over two sequential galettes, with the drawing of the texturized yarn in this case taking place analogously to the drawing of the threads prior to the texturizing unit.
With respect to the texturized yarn it is also appropriate, for the above named reasons, when the texturized yarn wraps around each of the galettes between 5 and 20 times, and in particular between 6 and 10 times.
When carrying out the method of the invention, the texturized yarn can leave the texturizing unit with a speed between 300 m/min and 500 m/min, in particular with 400 m/min.
~, In order to enable the formation of adequate loops of the effect thread during the texturizing process, it is of advantage when the speed of supply of the effect thread is higher than the speed of supply of the ground thread, so that in the finished thread the length of the processed effect thread is ultimately greater than the length of the processed ground thread.
It is preferred when both the effect thread and the ground thread are supplied at a speed which lies above the speed with which the texturized yarn leaves the texturizing unit.
The speed of supply of the ground thread preferably lies between 4 % and 8 %, and in particular approximately 6 % above the speed with which the texturized yarn leaves the texturizing unit.
The speed of supply of the effect thread preferably lies between 14 % and 20 %, and in particular between 16 ~ and 18 % above the speed with which the texturized yarn leaves the texturizing unit.
The texturizing unit, which is preferably formed as a texturizing nozzle, can, for example, be operated with a pressure between 6 and 14 bar.
It is of advantage when the ground thread is treated with water prior to the texturizing unit, with the water throughput amounting, for example, to between 0.1 l/h and 1 I/h, and in particular to approximately 0.2 l/h. Normal drinking water can, for example, be used for the water treatment of the ground thread, with the drinking water having previously been passed through an active carbon filter.
The ground thread and/or the effect thread can consist of polyester, polyamide, polyamide 6, polyamide 6.6, polyamide 4.6, polyethylene and/or viscose.
Instead of using only one ground thread and one effect thread it is alternatively possible to supply one ground thread and two effect threads, or two ground threads and one effect thread, or two each of the ground and effect threads to the texturizing unit.
In order to ultimately produce a sewing thread from the thread manufactured in accordance with the invention, the texturized yarn can be twisted, in particular after it has been heated. The twist amounts, for example, to between 150 and 600 and in particular to between 300 and 500 turns per meter.
Protection is also claimed in the context of the present application for yarns or sewing threads manufactured in accordance with the invention.
Further preferred embodiments of the invention are set forth in the subordinate claims.

BRIEF DFSCRIPTION OF THE DRAWING
The invention will be described in the following with reference to an embodiment and to the single Figure, which shows in schematic illustration the individual stations of an apparatus for carrying out the method of the invention.
The ground thread 1 is taken off a supply reel 2 during the operation of the apparatus. In analogous manner, the effect thread 3 is taken off a second supply reel 4.
The ground thread passes from the supply reel 2 to a first galette 5, around which the ground thread 1 is wrapped several times in helical manner. From the first galette 5, the ground thread 1 is tensioned to a second galette 6, around which it is likewise wrapped several times. In analogous manner, the effect thread 3 is guided via a third galette 7 and a fourth galette 8.
Following the second galette 6, the ground thread I passes to a wetting station 9, at which it is wetted with water.
The wetted ground thread 1 and also the effect thread coming from the fourth galette 8 are thereafter jointly supplied to a texturizing nozzle 1 0, in which the two threads 1,3 are swirled together.
The texturized yarn 11 leaving the texturizing unit is supplied via a fifth galette 12 to a heating device 13, from where the heated texturized yarn 11 passes to a sixth galette 14.
The texturized yarn 11 is again wrapped several times around each of the galettes 12 and 14.
From the sixth galette 14, the texturized yarn is led to a winding-up reel 15.
The described apparatus can, for example, be operated in the following mode, with the named parameters naturally being variable in the above named ranges.
The ground thread I is taken off the supply reel 2 with a speed of approximately 240 m/min and supplied to the first galette 5.
In corresponding manner, the effect thread 3 is taken off the supply reel 4 with a speed of approximately 310 m/ min and supplied to the third galette 7.
The ground thread has a fineness of approximately 160 dtex, while the effect thread has a fineness of approximately 90 dtex.
The second galette 6 runs faster by a factor of 1.8 than the first galette 5, whereby a corresponding draw of the ground thread 1 results. The fourth galette 8 runs by a factor of 1.5 faster than the third galette 7, whereby a corresponding draw of the effect thread 3 also results here.
The second galette 6 is heated to a temperature of 240~C, so that a corresponding heating of the ground thread I is brought about.
In corresponding manner the fourth galette 8 is designed for a temperature of 200~C for the heating of the effect thread. The first galette 5 and also the third galette 7 are both not heated.
In the wetting station 9 the drawn and heated ground thread is wetted with water, with a water throughput of 0.7 l/h being used here.
The texturizing nozzle 10 is operated at an air pressure of approximately 7 bar.
The swirled and texturized yarn 11 is drafted between the fifth galette 12 and the sixth galette 14 by a factor of 1.01, which is brought about in that the sixth galette 14 runs faster than the fifth galette 12 by a corresponding factor.
In the heating device 13 arranged between the two galettes 12, 14, the texturized yarn 11 undergoing the drafting process is heated to a temperature of approximately 300~C.
The texturized yarn leaves the texturizing unit 10 with a speed of approximately 400 m/min and is taken up by the winding reel 15 with approximately the same speed.
